INTRODUCTION

1. This collection provides for the following classification of roofs:

simple roofs with rectilinear surfaces (single-pitched, gently sloping, non-ventilated with an unorganized catchment area, flat, combined with a slope of 2.5 - 10%);

roofs of medium complexity with rectilinear surfaces (hipped, hip four-slope, hip with a fracture of slopes and mansard, half-hip, gable, gable with a lantern, four gable, as well as multi-slope roofs of various shapes in terms of L- and T-shaped, folded, roofs from oblique surfaces , roofs combined with a slope of St. 10%);

complex roofs with curved surfaces (domed, vaulted, cone-shaped, spherical, spire-shaped, cross-vaulted roofs).

2. The norms of this collection take into account the coating of solid surfaces with rolled materials, profiled asbestos-cement sheets of ordinary, reinforced and unified profiles with a coverage area of St. 200 m2. With a smaller coverage area H.vr. and Rass. multiply by the coefficients given in the table.

Covering parts of the roof of one building lying on various levels and not interconnected by the coating material, is normalized separately in accordance with the area of each part of the coating.

When determining the coverage area (for all types roofing materials) the area occupied by pipes, firewalls, parapets and ventilation units, from total area coverage is not excluded; the coverage of firewalls, parapets and ventilation units is rated separately.

Standing folds when covering individual structural elements with roofing sheet steel and wrapping around the bars when covering with rolled materials along the bars when measuring the area are not taken into account.

3. Covering of roofs of simple and medium complexity, lining of junctions with roofing steel, covering of cornices, gutters is provided with a slope of slopes up to 70%, except in special cases. When covered with asbestos-cement sheets of roofs with a slope of St. 70% N.T. and Rass. multiply by 1.35 (HF-6).

Rules for coating complex roofs with curved surfaces apply regardless of the slope.

4. The covering of firewalls and parapets, as well as the installation of caps, umbrellas and deflectors are provided directly from the roof or from ready-made scaffolds.

When working from portable ladders, ladders, etc. N.vr and Rass. multiply by 1.15 (HF-7).

When working from suspended cradles - by 2 (HF-8).

5. When covering window sills and projecting parts on facade walls in the process of erecting walls N.vr and Rass. multiply by 1.1 (HF-9).

6. When preparing and installing elements, the norms provide for the use of new roofing sheet galvanized steel with a mass of 1 m 2 - 4 kg.

With a mass of 1 m 2 roofing steel up to 4 kg or St. N.T. and Rass. respectively increase or decrease for every 0.5 kg of sheet weight by 10% (HF-10).

7. The norms of the collection provide for the carrying and movement of materials and products at a distance of up to 30 m inclusive. Bringing materials to a distance of St. 30 m should be normalized on Sat. E1 "Intra-construction transport work".

8. The standards for covering roofs with rolled and asbestos-cement materials, covering individual elements and lining junctions with roofing sheet steel are not taken into account and are standardized according to § E7-6.

9. The norms of the collection provide for the production of work at a height of up to 15 m from ground level. When performing work at the height of St. 15 m for each subsequent meter of height L.T. and Rass. increase by 0.5% (for example, when performing work at a height of 25 m N.T. and Rass. increase by (25 - 15) ? 0.5 = 5%, i.e. multiplied by 1.05).

10. Coating slopes are taken in %. A slope of 100% corresponds to an angle of 45°.

11. Professions "roofers by roll roofing and on roofs made of piece materials” and “roofers on steel roofs» are referred to as “roofers” for short; "insulators on waterproofing" and "insulators on thermal insulation" - "insulators".

12. The norms of the collection provide for the performance of work in accordance with the requirements of SNiP II-26-76 "Roofs"; SNiP III-20-74 "Roofs, waterproofing, vapor barrier and thermal insulation" and SNiP III-4-80 "Safety in construction".

APPROVED by the Decree of the State Construction Committee of the USSR, State Committee USSR on labor and social issues and the Secretariat of the All-Union Central Council of Trade Unions dated December 5, 1986 No. 43/512/29-50 for mandatory use in construction, installation and repair and construction work.

Introduction

1. This collection provides for the following classification of roofs:

simple roofs with rectilinear surfaces (single-pitched, gentle, non-ventilated with an unorganized catchment area, flat, combined with a slope of 2.5-10%);

complex roofs with curved surfaces (domed, vaulted, cone-shaped, spherical, spire-shaped, cross-vaulted roofs).

2. The norms of this collection take into account the coating of solid surfaces with rolled materials, profiled asbestos-cement sheets of ordinary, reinforced and unified profiles with a coverage area of St. 200 m2. With a smaller coverage area H.vr. and Rass. multiply by the coefficients given in the table.

The coverage of roof parts of the same building, lying at different levels and not interconnected by the coating material, is standardized separately in accordance with the area of each part of the coating.

When determining the coverage area (for all types of roofing materials), the area occupied by pipes, firewalls, parapets and ventilation units is not excluded from the total coverage area; the coverage of firewalls, parapets and ventilation units is rated separately.

Rules for coating complex roofs with curved surfaces apply regardless of the slope.

4. The covering of firewalls and parapets, as well as the installation of caps, umbrellas and deflectors are provided directly from the roof or from ready-made scaffolds.

When working with portable ladders, ladders, etc. N.vr and Rasts. multiply by 1.15 (HF-7).

When working from suspended cradles - by 2 (HF-8).

5. When covering window sills and protruding parts on facade walls during the construction of walls, N.vr and Rasts. multiply by 1.1 (HF-9).

6. When preparing and installing elements, the norms provide for the use of new roofing sheet galvanized steel with a mass of 1 m 2 - 4 kg.

With a mass of 1 m 2 of roofing steel up to 4 kg or St. N.T. and Rass. respectively increase or decrease for every 0.5 kg of sheet weight by 10% (HF-10).

9. The norms of the collection provide for the production of work at a height of up to 15 m from ground level. When performing work at the height of St. 15 m for each subsequent meter of height L.T. and Rass. increase by 0.5% (for example, when performing work at a height of 25 m, L.v. and Esc. increase by (25-15)´0.5 = 5%, i.e., are multiplied by 1.05).

10. Coating slopes are taken in %. A slope of 100% corresponds to an angle of 45°.

11. Professions "roofers on rolled roofs and on roofs from piece materials" and "roofers on steel roofs" are called "roofers" for brevity; "insulators on waterproofing" and "insulators on thermal insulation" - "insulators".
